discontinuous medial scries of three scales, the first small and touching 

 the rostral ; the second prefrontal the largest, in contact with its fellow, 

 separated from the canthals hy a series of scales; two canthal scales, 

 the second the larger, followed l)y five elongate superciliaries. the last 

 one the smallest ; six slightly ridged sui)raoculars, partially se])arated 

 from the frontals hy rui incomplete series of small scales and from the 

 superciliaries hy two series except posteriorly where there is a single 

 row ; frontals moderate in size, mutually in contact along their entire 

 inner horders ; occipital small, with a small scale immediately following 

 it, the two scales hordered on each side by two distinct parietals, the 

 inner about half the size of the outer, which is about five times the 

 area of the anterior occipital ; an enlarged, heavily ridged scale at the 

 outer posterior margin of the outer parietal ; no other conspicuously 

 enlarged post-parietals ; five upper and five lower labials to a point 

 below the center of the eye ; malar scales large and conspicuous, the 

 first two sul)equal and separated from the infralabials by a single row 

 of scales; temporal scales small and mostly uniform in size, those just 

 in front of the ear gradually enlarging, the upper one about three 

 times as large as the surrounding scales ; anterior border of the ear 

 with five or six unequal projecting scales, the longest reaching one- 

 third of the distance across the tympanum. Dorsal scales moderately 

 large, imbricate, very slightly mucronate ; laterals smaller than the 

 dorsals, the gradation in size being very gradual ; ventrals slightly 

 smaller than the dorsals, smooth, their posterior borders slightly den- 

 ticulate ; about 6 1 dorsal scales from the occiput to a point directly 

 above the vent ; about 14 dorsal scales equivalent to the distance from 

 snout to occiput ; nuchal scales moderately small, those behind the ear 

 and in the shoulder folds like the dorsals but very small ; no lateral 

 fold. The adpressed hind limb reaches to the center of the eye. Digits 

 compressed, the fourth toe with 24 tricarinate lamellae, the scales on 

 the upper surfaces of the limbs relatively small ; a very distinct but low 

 dorsal crest beginning at the occiput and continuing without inter- 

 ruption to the end of the tail, increasing on the posterior part of the 

 body and becoming much higher on the tail ; the caudal scales keeled 

 and highly mucronate ; no verticils ; tail slightly compressed. The keels 

 of the dorsals and laterals converge posteriorly. A pair of widely- 

 separated and very inconspicuous postanals in the male.
